Crown PCC-160 Unidirectional Boundary Microphone

PCC-160 Unidirectional Boundary Microphone description:

The Crown PCC-160 (Phase Coherent Cardioid) is a surface- mounted halfsupercardioid microphone intended for professional applications on stage floors, lecterns, conference tables, and news desks wherever improved gain-before- feedback and articulation are important.

Similar to the Pressure Zone Microphone (PZM), the PCC is designed to be used on a relatively large boundary surface. Unlike the PZM, the Phase Coherent Cardioid uses a subminiature supercardioid mic capsule. Its directional polar pattern improves gain-beforefeedback, reduces unwanted room noise and rejects sounds from the rear. Surface- mounting creates a half-supercardioid polar pattern and increases directivity 3 dB.

Since the microphone capsule is placed on a boundary, direct and reflected sounds arrive at the diaphragm in-phase. This coherent addition of direct and reflected waves increases sensitivity 6 dB and prevents phase cancellations. The mic capsule is small enough to ensure phase coherency up to the highest frequencies in the audible spectrum, resulting in a wide, smooth frequency response free of phase interference. Clarity and reach are also enhanced.

Self- contained electronics eliminate the need for an in-line preamp box. The PCC-160 can be phantom powered directly from the console or other remote power source providing 12 to 48 volts. If battery power is required, a battery supply unit can be inserted anywhere in the mic line right up to the console or mixer. A bass tilt switch allows the user to tailor the low-end response for particular applications.

Thanks to its low profile and black finish, the microphone becomes almost invisible in use. A side-mounted connector complements the form factor of the PCC-160, allowing the unit to be placed effectively at the stage edge, at the top of a lectern or in other tight spots. If desired, the cable can be hard-wired for bottom entry.

The alternative PCC-160W is finished in off-white to blend with church altars and other surroundings where lighter color is appropriate.

The heavy-gauge, all steel body protects the unit from accidental abuse. Permanent mounting is enabled by screw holes in the base. Engineering attention-to-detail has assured years of trouble- free use from this reliable microphone.

Capable of withstanding up to 120 dB SPL without distorting, the PCC-160 will never overload in practical use. Its electret condenser capsule provides a wide, smooth frequency response from 50 Hz to 18 kHz. RFI suppression is included. Self-noise is low, and sensitivity is very high to override mixer noise in distantmiking applications. Output impedance is 150 ohms, balanced.
